ADJUSTABLE HYDRAULlC CYLINDER FOR FLANGlNG-PRESSES.

I SPECIFICATION forming part of Letters Patent No. 550,916, datedDecember 3, 1895.

Application filed September 20, 1895. Serial No. 563,061. (No model.) i

To all whom it may concern.-

Be it known that I, EBENEZER A. W. JEF- FERIES, a citizen of the UnitedStates, residing at the city of Philadelphia, in the county .ofPhiladelphia and State of Pennsylvania,

have invented certain new and useful Improvements in AdjustableHydraulic Cylin ders for Flanging-Presses, of which the following is aspecification.

My invention has relation to a hydraulic fianging-press of the type inwhich the flanging-die is carried by the ram or piston of a hydrauliccylinder; and it relates to the construction and arrangement of suchhydraulic cylinder, whereby the same may be adjusted in the head-platecarrying or guiding the cylinder for the purpose of fianging fire-boxmouths of locomotive-boiler fronts and other similar articles.

The principal objects of my invention are,

first, to provide in a hydraulic flanging-press a die adapted to flangefire-box mouths for locomotive-boiler fronts and other similar articlesin which the position of the interior opening is variable, and, second,to provide in a hydraulic flanging-press a die carried by the piston ofa cylinder adjustable laterally or longitudinally or in both directionsin the head-piece of the press.

My invention, stated in general terms, consists of a hydraulic cylinderoperating a flanging-die adjustable in the head-piece of the press; andmy invention further consists of an adjustable die-carrying cylinder forhydraulic flanging-presses constructed and arranged in substantially themanner hereinafter described and claimed.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, forming part hereof, and in which- Figure l is a top or planView of the headpiece and supporting-standards of a hydraulicflanging-press embodying features of my invention and illustrating inconnection with said head-piece the laterally-adjustable diecarryinghydraulic cylinder in said headpiece. Fig. 2 is a front elevation of theupper part of a hydraulic press embodying features of my invention andillustrating the head-piece and adjustable die-carrying cylinderadjustable longitudinally therein;

Fig. 4is a top or plan view of the headandFigs. 5 and 6 are respectivelyfront and side views of an 'unflanged and flanged blank for a fire-boxmouth of a locomotive-boiler front.

Referring to the drawings, a represents the head-piece or table of ahydraulic flangingpress screwed or otherwise secured to the upperportion of the columns or supportingstandards I). At approximately thecenter of the head-piece or table a and extending through the same isformed a slot d, which, as shown in Fig. 1, extends laterally across thehead-piece or table a, or a slot e may be formed in said table at,extending longitudinally therein, as illustrated in Fig. 4. These slotseach cross the middle or center of the table a and are slightly largerin width than the external diameter of the hydraulic cylinder f, whosepiston or ram carries the flanging-die. (Not shown.) Within the slot (lor 6 may be located the cylinder f and secured in any desired positiontherein.

The means which may be employed is as follows: The head-piece a isprovided on either cured to the plate (Z or e and the head of thecylinder secured to the table a by screwing down upon the plate the nuts(1 or e of the bolts, thus clamping the plate and cylinder to the table.When the cylinder is to be shifted, the nuts of the bolts are loosened,and the heads and stems of the bolts are thereby permitted to move inthe slots or grooves (Z or e of the table.

In flanging the blank h, and'particularly the internal opening 11, of afire-box mouth for a boiler front or similar blanks it is necessary thatthe die carried by the piston of the hydraulic cylinder be adjusted soas to register with said opening *6, because this opening in blanks ofthis character varies in its position even in boiler fronts of the samesize and shape. To permit of the adjustment of such die, is provided theadjustment laterally or longitudinally of the hydraulic cylinder f inthe piece or table a, and thus to bring the die carried by the piston ofthe hydraulic cylinder into any desired position to register with the pThe successive po- 1 sitions of the cylinder f are indicated in fullopenings 1' of the blank.

and dotted lines in Fig. 1 of the drawings.

Having thus described the nature and objects of my invention, What Iclaim as new,

and desire to secure by Letters Patent, is

1. In a hydraulic flanging-press, a head/ piece or table, a hydrauliccylinder and piston or ram carrying a flanging die, and means foradjusting said cylinder in said head piece or table to vary the positionof said die, substantially as and for the purposes described.

2. In a hydraulic flanging-press, a headpiece or table havinglongitudinal or lateral openings and a hydraulic cylinder adapted to beadj ustably secured in the openings of said to said head-piece by saidbolt to secure the cylinder, substantially as and for the purposesdescribed.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing Witnesses.
